Dynamic vibration absorber suitable for high-temperature pipeline

The dynamic vibration absorber comprises a mass ring and a pipe clamp, the pipe clamp is arranged in the mass ring, the periphery of the pipe clamp is connected with the inner wall of the mass ring through a plurality of damping assemblies evenly distributed on the circumference, springs are arranged along the pipe clamp, and mass pieces are symmetrically installed on the mass ring; the damping assembly is at least one of a spring or metal rubber; at least one mass sheet is stacked; the vibration absorber solves the vibration problem of a high-temperature pipeline when pulsation is generated during gas transportation, the vibration absorber is simple in structure, the mass can be finely adjusted by increasing or decreasing the mass pieces, the pipeline vibration absorption function is achieved, meanwhile, potential safety hazards caused by the fact that parts are prone to being lost during replacement and maintenance are reduced, the mass of the vibration absorber can be adjusted within a certain range, and t
